well, that's interesting. The Mk2 I just got a few days ago...the magazine in the pistol had the new magazine with the vertical rib, but the two extras - no rib. Hope that isn't important, and also a bit weird that the Mk2 is new, the design change was over a year ago, and I'd still get old style mags?

It's no biggie as long as they work, they are supposed to work in both models.

As with all production changes, some of the old style will be around for a while and remain in circulation. If I had to guess, they probably had the (old) spare mags in the case already, awaiting the switch over to the MkII. Then, once the new gun rolled out, they put in a new mag (probably also fresh from the production line), dropped it into the case, & shipped it out.

It's only a big deal if you're one of the OCD types who HAVE to have the same mags :laugh: Even then, you can probably just trade with someone to get all the same type.

Hello
I am new to the forum but not FN products. I just picked up a new five-seven MKll. It goes nicely with my PS90 and FS2000.
My thoughts are about the mags. In the box I received one second gen mag with the ridge on the front lip running down the inside length of the mag. The ridge runs between the bullets. The other two mags do not have the ridge and are first gen mags. I called FN and a tech stated they are the same but for the ridge and work the same. The ridge was there to simplify production. He also stated they have a stockpile of the older style and just pick up mags to put in the pistol boxes. Dosen't make any diff in performance.
Anyone have any knowledge as to if one is more reliable than the other.
I know on mine the newer ridged one is more difficult to load with shells.
Thanks.

It is only the front lip that breaks. The main curved ones are steel reinforced. As you can see in this pic it's the front lip that the rounds are dragged across as they chamber is the breaking point. This mag's lips had broken and I installed our protector.

Hi All:
I read this forum just about every other day, but don't post a lot. I saw an ad from CDNN about a month ago for the extensions from CMMG to make the mags 30 rounds for $9.95 and $4.95 shipping. I could not resist and bought 2 at this price. As I live in the desert about 45 miles away from Las Vegas it was a while before I could test them because of the wind here. Took them out last week and they performed flawlessly. Would recommend the for purchase.

Is FN warranty'g the old style mags if the lip breaks off?

NOPE and they refuse to sell just the magazine bodies.

Actually Jay they do warranty them if they break. This last year I had 2 break that I had not had the time to modify them with your kit yet. I called FNH and they had me mail them the mags. They sent me 2 of the new versions as replacements. It took about 3 weeks from start to finish.

I would like to share a brand new clip i received from cheaperthandirt for my MKii. it's suppose to be an OEM, this clip looks different from all the ones posted and i also wanted to get some input on the space between the clip and the handle along with the separation down the middle when looking down the clip.
Thanks again!
